前向き住民ベース2192名の心血管疾患無し、70-79歳対象
Auer らはベースラインの心電図異常、新規異常発生、持続ECG異常が冠動脈性心疾患イベントリスク増加と関連するかを検討。
平均6.4年フォローアップで、majorあるいはminorな心電図異常は、冠動脈リスク増加と関連し、イベント予測としては従来の心血管リスク要素予測より優れていた。

Minnesota Code (MC)
Criteria for major prevalent ECG abnormalities were
major 心電図異常:
・ any of the following: Q-QS wave abnormalities (MC 1-1 to 1-2-8)
・ left ventricular hypertrophy (MC 3-1)
・ Wolff-Parkinson-White syndrome (MC 6-4-1 or 6-4-2)
・ complete bundle branch block or intraventricular block (MC 7-1-1, 7-2-1, 7-4, or 7-8)
・ atrial fibrillation or atrial flutter (MC 8-3)
・ major ST-T changes (MC 4-1, 4-2, 5-1, and 5-2).
minor 心電図異常: minor ST-T changes (MC 4-3, 4-4, 5-3, and 5-4)
Figure 1. Kaplan-Meier Estimates of CHD Cumulative Hazard Over Time of Any vs No ECG Abnormality
CHD indicates coronary heart disease; ECG, electrocardiographic. Any ECG abnormality included minor, major, or both. All 351
CHD events were included.
